Abstract

In recent decades, the demand for underground space has been increased. Deep excavations are required to meet the demand, and, in many cases, excavation sites are in close proximity to existing structures. A major concern in these construction activities is to predict the lateral wall deflections and the ground surface settlements in the design stage. While numerical methods are often applied for the prediction of these movements, there are demerits because of the complexities of these methods, and it is desired to estimate the approximate deflections in a primary design stage. In this paper, a simplified procedure for the prediction of maximum lateral deflections of diaphragm walls is proposed, based on the research of empirical correlations concerning with factors affecting the behavior of walls in 52 case studies.
